ELECROW CrowPanel Advance 3.5“ HMI| ESP32-S3 AI-Powered IPS Touch Screen 480×320 With Acrylic Case

The Elecrow CrowPanel Advance 3.5″ HMI is a cutting-edge display solution for IoT and embedded systems. It features a 3.5-inch IPS capacitive touch screen with a resolution of 480×320, offering clear and vibrant visuals with a 178° viewing angle and 400 cd/m² brightness. Powered by the ESP32-S3-WROOM-1-N16R8 module, it includes a dual-core Xtensa 32-bit LX7 processor running at up to 240MHz, ensuring robust processing capabilities. Memory specifications include 512KB SRAM, 8M PSRAM, 16M Flash, and 384KB ROM, supporting complex applications.

A key highlight is its AI functionality, enabled by an onboard microphone and speaker, supporting voice command interaction, voice recognition, and speech synthesis. This enhances user interaction in smart home and industrial settings. The display also features a real-time clock (RTC) function for accurate timekeeping, crucial for time-sensitive applications.

The replaceable wireless module design is a significant advantage, supporting various protocols such as 2.4GHz Wi-Fi 802.11a/b/g/n, Bluetooth 5.0 and BLE, and optional modules like Zigbee, LoRa, nRF2401, Matter, Thread, and Wi-Fi 6. This flexibility allows developers to customize connectivity based on project needs, with pre-installed firmware supporting multiple communication protocols.
